DYEING APPARATUS.

Specification of Letters-Patent.

1 Patented Apr. 1 1913.

Application filed September 28, 1912. Serial No. 722,831.

To all whom it may concern.-

- features thereof, to mechanism for pos'i-' tively and'progressivelychanging the relation of the material to be dyed to its support.

One of the objects ofthe present invention is to provide a simple andpractical device of the above character.

Another object is to provide efficient mechanism for progressivelymoving the material to be dyed relatively to its support and maintainingthe material in its altered position. 3

A further object is to provide an inexpensive .device of the abovecharacter, the

parts of which will be unaifectedby contact with the dye liquor.

Other objects will be in part obvious and in part pointed outhereinafter.

Ihe invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawing, wherein is shown one of various possibleembodiments of this invention, Figure 1 is-a longitudinal sectional viewin elevation, showing such parts of a dyeing apparatus as are necessaryto understand the present invention and its application; and Figs. 2 and3 are detail elevat-ional views at right angles to each other showing aportion of the pres ent invention on an enlarged scale.

Similar reference characters refer' to simi lar parts throughout theseveral views, of the drawing.

In order that the present invention and certain objects thereof may bemore readily understood, it may here be noted that in dyeing apparatusof the general character illustrated it is desirable to alter or changethe position of the material to be dyed, such as,

for example, skeins of yarn, at regular intervals in order that they maybecome thoroughly and equally permeated by the dye liquor, thuseliminating stick marks.

If it be attempted to employ spring-actuated pawlan'd ratchet mechanismfor maintalnmg the change in position, it will be found in practice thatthesprings used de teriorate rapidly from the action of the dye liquorthereon and their replacement is a source of constant annoyance andexpense. In the present invention trouble of this character is obviatedby providing a .con-

struction which is reliable in action and efficient in use.

Referring now tothe drawing in detail,

and more particularly to Fig. '1, 1 denotes a rectangular tank, providedwith a. false bottom 2, adapted to contain dyeyliquor, which iscirculated about the tank in the direction of the arrows underthe falsebottom 2 by means of jets of steam issuing from openings in a transversepipe 3. The up or part of the tank is provided with a suita le housing4, having doors 5 atopposite sides thereof to permit the charging anddischarging of a rotary skein-supporting frame 6 mounted'on a shaft 7extending transversely of the tank. This framecomprises two wheels, onlyone of which 8 is shown in the sectional view, revolving adjacenttheside wall 9 of the tank. Between these wheels and extending parallel tothe shaft 7 are a plurality of sticks, notshown, upon which are mountedthe skeins'o'f yarn to be dyed.

As this general mechanism so far described is substantially the same asthat shown in the patent to Klauder, No. 411,504, of Sep-' tember 24,1889, it isthought that a further detail description thereof isunnecessaryz Mounted at regular intervals about the reel. 8. At theoppola a star-- a detent- 18 will hus he i a 1, i is, he starwheel I?will coact -Jith detent 18 and be turned through a quarter of arevolution.

in order to prevent a return of the starwheel to its former positionafter passing the detent 18, there is provided a gravityactuated pawl19, moving in a vertical plane, adapted to coact with the teeth of theratchet wheel 13. This pa'wl 19 is provided with a 20 counterweight 20,preter'ably cast integrally therewith, projecting downwardly from theunderside thereof, to shift the center of gravity of the pawl, Thiscounterweight 'coacts with a projecting log 21 on the wheci 5 8 toprevent the pawl 19 from swinging com pletelyaround its pivot 22 as theWheel. revolves.- From an inspection of the drawing it. will be seenthat the pawl engages the ratchetteeth for a material time before andafter passing the detent 185'durin'g which time the yarn'is subjected tothe greatest strain. For example, while the star-wheel Y is being turnedby the detent 18 to turn the square stick and yarn supported thereby to5 a new iposition, the skein is slightly tens ed along one, sidetemporarily and it it were not for the pawl engaging the ratchet therewould be a tendency for the square stick to return to its formerposition 4o tension, however, in theyarn is relieved almost immediatelyby the turning of the support or. stick for the other end of the skeinfitting within the round holes 533 locate'd at regularintervals about aninner flange 24 As the wheel 8 continues to re volve to carry yarn intothe dye liquor, the pawl automatically disengages itself from theratchet teeth as its center of gravity shifts relatively to the otherside of a ver so tical plane through the pivot, thereby inittir acertain freedoin'oif movement to the "n as it passes tl'irough the dyeliquor. the construction and operation of ma chines of this cha actorare Well known to those familiar with the art, is believed to beunnecessary to go into a detailed description thereof It is. supfhcientto state that a construction of this character is reliable andefi'icient in operation. and is cheap to manufacture and install. Theconstruction does away with the use of springs and delicate parts whichare so easily, afiected by t liquor and result in the constant 8111? andexpens of replacing and repairing. As many changes could be made in theabove construction and many apparently widely diti erent embodiments ofthis inveni102; could be made WltllOllt departing from the scopethereof, it is intended that all-mat ter contained in the abovedescription Patent is:
